103R-332F

Overview

The Delevan 103R-332F is an unshielded surface-mount RF inductor with a nominal inductance of 3.3 µH and a tolerance of 1%. It features a maximum DC resistance of 1.4 Ω and a rated current of 260 mA. The component utilizes a phenolic core and is housed in a 1010 (2525 metric) rectangular package measuring 2.54 mm in length, 2.54 mm in width, and 1.91 mm in height. It operates within a temperature range of -55 °C to +125 °C.

Feature Summary

• Unshielded SMD construction for compact RF circuit integration
• Phenolic core material providing stable inductance characteristics
• High precision 1% tolerance for accurate signal filtering
• RoHS compliant lead-free termination style

Applications

• RF signal processing circuits
• Impedance matching networks
• General purpose RF filtering applications

Procurement Notes

Verify the specific manufacturer designation, as API Delevan assets are managed by different entities. Confirm RoHS compliance status directly with the supplier, as documentation varies. Ensure the 1010 package dimensions match your PCB footprint requirements. Validate the 1.4 Ω DCR specification against your circuit's power budget constraints before finalizing procurement.

Selection Notes

Select this component when a precise 3.3 µH value is required in a small surface-mount form factor. The unshielded design necessitates careful layout consideration to minimize electromagnetic interference with adjacent traces. Verify that the 260 mA current rating exceeds the maximum expected operating current to prevent saturation or excessive heating during continuous operation.

Part Context

This part belongs to the Delevan fixed inductor family, specifically designed for radio frequency applications. It shares the 1010 package standard with other series members but is distinguished by its specific 3.3 µH value and tight 1% tolerance. The unshielded architecture differentiates it from shielded variants used in high-density interference environments.

Replacement Considerations

The 103-332F is a through-hole axial variant with identical electrical parameters but different mounting requirements. The 103R-332J offers the same inductance but with a wider 5% tolerance. Direct pin-compatible replacements require verifying the exact package dimensions and terminal configuration.
